Abstract: Some embodiments of the present disclosure provide the design and manufacture of an ultra-small chip assembly. The ultra-small chip assembly comprises a die, a plate-like back electrode disposed on the back-side of the die, and one or more plate-like positive electrodes disposed on the front-side of the die. The ultra-small chip assembly is configured such that one end of the plate-like back electrode extends beyond a first side of the die, and each of the one or more plate-like positive electrodes includes an end which extends beyond a second side of the die. By attaching both the plate-like back electrode and the plate-like positive electrodes on the surfaces of the die, and directly using the exposed ends of the plate-like electrodes as the lead-out electrodes for the chip assembly, the electrical connections outside of the die only occupy a very small volume.

Abstract: A voltage regulator that modulates the switching of a switching circuit to regulate the output voltage level supplied to a system. The regulator uses a comparator circuit to compare a reference signal to an analog signal derived from the output voltage of the regulator, and outputs a binary signal based on the comparison. The regulator may use a counter circuit that interrogates the binary signal from the comparator circuit and generates a counter signal proportional to, for example, the duration of the binary signal when it stays in one of the two binary states. The regulator then uses a trigger circuit that generates a signal based on the counter signal to effectuate the modulation of the switching of the switching circuit. The reference signal may be modified by a hysteresis level adjuster to force a triggering event at the switching circuit.

Abstract: In one embodiment, the present invention includes a charge pump circuit. The charge pump circuit comprises a plurality of terminals, a plurality of switches for selectively coupling the plurality of terminals, and a control circuit. A first input terminal receives a first reference voltage and a second input terminal receives a second reference voltage. First, second, third, and fourth flying capacitor terminals and the first and second input terminals are selectively coupled together in different configurations. The control circuit selects the switches to actuate according to a cycling of at least three phases of configuration. The cycling shifts the first and second reference voltages to provide dual power supply rails.
